Hi George,

I've also recently acquired a Harrison lathe (ex school) that I've converted to single phase using an inverter - I'm still trying to learn how to use it, so would appreciate a copy of your training DVD if you can manage an extra copy. I'll pm you.

Thanks,

John

Image Thanks George,
I've attached a photo of the Harrison lathe.
It's an ex-school lathe, and I removed all the original 3 phase wiring etc from the control box & fitted a variable frequency inverter with an external speed control with reverse & jog. It all works very well, I'm just starting to get the hang of using it.

Thanks George,
the DVD arrived today & is much appreciated.
Good basic training which shows what can be done on a miniature Chinese lathe - I was impressed.

Does the VFDI work well? Do you use the original 3 phase motor?
Thanks,

hi,

on my lathe, i run a 3 phase motor, through an inverter, the inverter is 1 x phase in and 3 phase out. the variable speed makes using the lathe very user friendly, no swapping gears or belts like the good old days. makes the control exceptionally easy. always using different speeds for different materials and operations.

hope this helps

regards

george

Hi,
the original motor was 415volt only, but I managed to pick up a virtually new (still boxed) dual voltage 2HP motor from Gumtree, which fitted perfectly. I wired it for 240Volt 3 Phase, and the VFD works perfectly.

Since then I've acquired a Myford S7 from a deceased sale, and although it had a single phase motor the first thing I've done is convert it to 3 Phase with a VFD. I'm still restoring the Myford, but wouldn't consider not having variable speed. It transforms the lathe - especially compared to changing belt drives!

I'm not sure I need two lathes, but then I don't actually need eight bikes either, and they're different from each other...
